Application filed September 14, 1920. Serial No. 410,297.

To (rZZwhom it may concern:

Be it known that I, DOIN KwoN, a c1t1- zen of Korea, and a resident of Honolulu, 1n the Territory of Hawaii, have invented a new and Improved Sewing-Machine Attachment, of which the following is a full, clear, and exact description.

This invention relates to improvements in sewing machine attachments, more particularly to an attachment adapted to be con-- nected to the head of the sewing machine and support the extension board of a machine when the latter is folded upwardly, preventing injury to the board and to the The ordinary Singer type of sewing machine on the market is provided with a hinged extension board, which when the machine is to be dropped, folded, or covered, is swung upwardly against the head of the machine, and by-reason of the contact of said board with the head of the machine, the surface of the board is disfigured and roughened and more or less damaged which does or may result to the machine by contact with the board therewith, and it is the purpose of my invention to provide an attachment which may be connected with the head of the machine and which will not interfere in any way with the operation of the machine, but which will serve as a support for the board when it is swung upwardly as above indicated.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawing:

Figure 1 is a view in front elevation illustrating a sewing machine with my improved attachment in position thereon.

Fig. 2 is a view in longitudinal sectlon through the center of my improved attachment; and

Fig. 3 is a plan view of my improved 'at tachment.

1 represents the table and 2 the head of a sewing machine of the ordinary Smger type in common use on the market. 8 is an extension board which is ordinarily hinged to the table asshown at 4;, so that this board when swung to a horizontal position will operate as an extension of the table and when it is not desired as an extension, it is folded upwardly to the inclined position of Fig. 1 and constitutes a portion of the sewing machine when the latter is folded or dropped as is well understood in the art.

5 represents my improved attachment which consists of a metal plate fitted against the outer face of the head 2, and preferably bent slightly at its lower end so as to extend under the head as shown at 6. This plate 5 is provided with openings 7 to re ceive screws 8 which are found on the machine in general use to securely clamp the plate to the head, and a slot 9 is provided on the attachment for the accommodation of the take up arm 9, and a notch 10 is provided in the plate for the accommodation and guidance of the thread 11.

The plate 5 at its upper end is made with an outwardly and upwardly projecting tongue 12 on which a rubber or other form of cushion 13 is secured, and this cushion 13 is in such position thatit will receive and contact with the board 3 when the latter is folded, holding the board at, outer engagement with any metallic portion of the machine, and hence preventing injury to the surface of theboard or other parts of the machine.

My improved attachment may be connected to the machine by anyone and does not require skilled labor, and when once in position will serve as a protection both for the board and the machine.

While I have illustrated what I believe to be a preferred embodiment of my invention, I would have it understood that I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope ofthe appended claims.

plate to receive the hinged extension board thereagainst and prevent contact of the board with the head of the machine.

2. The combination with a sewing ma- 5 chine having a head and -a hinged extension board, of an attachment'comprising a plate having screw receiving openings therein whereby said plate is secured to the outer face of the sewing machine head, said plate having a slot therein and a, thread guiding notch therein, an upwardly and outwardly projecting tongue on the plate, and a cushion. on said tongue adapted to receive and support the extension board when the latter is swung upwardly.
